Send the image as `multipart/form-data`, in the part `file`. The logo is printed on the NFSe PDF, so it must be a PNG or a JPEG (content type `image/png` or `image/jpeg`) of up to 1 MB. Uploading a new logo replaces the previous one. If the tax provider rejects the request, the error is returned with the provider's error `code` and a status of 400, 409, 422 or 502. ## OpenAPI ````yaml /api-reference/accounting.openapi.json post /realms/{realmId}/organizations/{organizationId}/tax-issuer/{taxIssuer}/logotype openapi: 3.0.3 info: title: Accounting version: 1.0.0 description: >- Portão 3 accounting API. Every endpoint requires a bearer token in the Authorization header (Authorization: Bearer ) unless its page states otherwise; see the Authentication guide. That requirement is not repeated per endpoint. Generated by tools/openapi from code (routes + security) and the hand-written spec (request/response bodies). NFSe issuance: the organization's tax issuer (setup, certificate, logo), its tax documents (issue, list, download, cancel, CSV batches) and the city special-tax-regime lookup. Every route validates path, query, body and multipart form through a zod Input class (`accounting/app/use-case/*/inputs`), which documents it; responses are the named interfaces in `accounting/app/use-case/*/outputs/*Response.ts`.
